PROBLEM TO BE SOLVED: To provide a reverse and reduction gear which can be steplessly decelerated.SOLUTION: A reverse and reduction gear 11 changes power of a main engine (engine) 10 mounted on a hull into forward, neutral or reverse output and transmits the same to a propeller 5 via an output shaft 15. The reverse and reduction gear 11 comprises a driving source 16 separately from the main engine 10, and a planetary gear mechanism 20 which synthesizes rotational powers of the main engine 10 and the driving source 16 and outputs the same to the output shaft. A rotation direction of the driving source 16 is reversible and a rotational speed of the driving source 16 is variable, and therefore, the reverse and reduction gear 11 enables forward and reverse rotation of the output shaft 15 and enables stepless acceleration/deceleration thereof.SELECTED DRAWING: Figure 2

    【課題】無段階で変速可能な減速逆転機を提供する。【解決手段】本願発明の減速逆転機11は、船体に搭載した主機関(エンジン)10の動力を前進、中立又は後進の出力に切り換えて、出力軸15を介してプロペラ5に伝達する。そして、減速逆転機11は、主機関10とは別の駆動源16と、主機関10及び駆動源16からの回転動力を合成して出力軸に出力する遊星ギヤ機構20とを備えている。駆動源16の回転方向が可逆であり且つ駆動源16の回転速度が可変であって、減速逆転機11は、出力軸15の回転を正逆転可能とするとともに無段階で増減速させる。【選択図】図2
